If you're encountering an app error, in some cases it can help to force close the app (quit) and reopen the app in order to refresh the app.
Here's how:
On the home screen of your Android phone, tap the 3 vertical lines in the lower left corner to display recently opened apps
Swipe up on the app you wish to close, or tap Close all to close all open apps
